RAIL CHAIR AND SFLICE PLATE.

Application filed September 3, 1827. Serial No. 217,378.

This invention relates to improvements in rail chairs and splice plates, the general object of the invention being to provide means for firmly holding the railsto the ties and for fastening the ends of the rails together, the parts being so arranged that rails can be quickly and easily put in place.

Another object of the invention is to so. form the fish plates'that they will clamp the ends of the rails together without the use of bolts and to providemeans whereby the spikes for the chairs and fish plates are driven through depending portions into the sides of the ties. 7

Another object of the invention is to make the fish plates and the chairs of sections which are so formed that a wedging action is set up whenthe sections are placed together which acts to clamp the rail or rails in place, while permitting expansion and contraction of the rails.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in Which:--

Figure 1 is a longitudinal sectional view through a portion of'a track showing my invent-ion in use. 2

Figure 2 is a plan view of Figure 1.

Figure 3 is a section on line 3-3 of Figure 4.

Figure 4 is a section on line 4-4: of Figure 2. p

Figure 5 is a section on line 5-5 of Figure 2. V

Figure 6 is a top plan view of a chair showing the sect-ions thereof partly separated.

Figure 7 is a horizontal sectional view through a pair of fish plates, showing the same partly separated.

In these drawings, A indicates a chair for fastening a rail B to a tie C, this chair comprising a pair of sections 1 and 2, each section being formed with an overhanging flange 3 for engaging the top side of one portion of the base of rail when the rail is ,seated'upon the chair, as, clearly shown in Figure 4:. The 1nner edge of each SGCtlOIllS inclined, as shown at 4, and adjacent the inclined edge, each sect-ion is formed with a dovetail groove 5 which forms a dovetail tongue 6 whichengages the groove, in the other section. The grooves open out at the inner end of each section, the outer end of each section being formed with a depending flange 7 which closes the groove. Thus when the two sections are pushed together with their tongues engaging the grooves, one section moves toward the other section so that the flanges 3 will set up clamping action on the base of the rail and thusclamp the rail in the chair. The flanges 7 engage the sides of thextie and spurs. 8 are formed on the flanges which penetrate the tie, as shown in Figure 3. 'Spikes9 are driven through holes inthe flangesinto the tie, as also shown in Figure 3,.to hold the chairtothe tie. .At the top of the inner wall of each flange 7 is an overhangingpart 10 which tits in a recess 11 in the inner end of the other section, when the two sections are brought together.

The fish plates 12 and 13, used for connectthe abutting ends of two rails together, are made similar to the sections of the chair, but the inner edges of the flanges 3 of the fish plates are extended upwardly, as shown at 14;, with their upper ends enlarged and shaped to fit the under side of the head of the rail, as shown in Figure 5. These extensions 12 are reinforced by the webs 15. These plates 12 and .13 are also formed with depending flanges '1' for engaging the sides of the ties and these flanges are provided with holes so that spikes can be driven into the sides of the ties. These flanges are also provided with the spurs 8. The fish plates are also formed with the outwardly extending ears 16 having spike receiving holes therein so that spikes can be driven into these cars into the tops of the ties, as shownv at 17.

When putting a track in position, onehalf of a chair is slipped between the rail and tie and. spiked and. then the other half slipped on from the wider end on the other side of the rail and spiked. As before stated, the pushing together of the two halves or sections of the chair sets up a clamping ac tion on the base of the rail so that after the chairs are spiked to the tie, the rail is firmly held in place. The fish plates are assembled in the'saine manner and these plates are held in position not only by the spikes in the sides of the ties, but also by the spikes passing through the ears 16 into the tops of the ties, these latter spikes acting to keep the ties from spreading. As will be seen, this form offish plate assembly will firmly hold the rail ends together Without the use of bolts so that it is not necessary to drill holes in the rails. By driving spikes into the sides of the ties, there is less danger of them Working loose and the ties will last longer, due to the fact that there are but few holes in the upper surfaces of the ties. When the Weight of a train comes on the rails, the fish plates will clamp the rails under their heads so that the rails are firmly held together Without the use of bolts and thus the rails are not weakened by having holes bored therein.

A Wear plate 18 is placed under each chair and pair of splice plates and each structure is also provided with a pair of depending parts 19 Which rest upon the Wear plate and a cen tral projection 20 which forms a fulcrum for a rail, as clearly shown in Figures 4 and 5.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.

What I claim is 1., Means for, fastening a rail to a tie of a track comprising a chair formed in sections, each section comprising a base and an overhanging flange, the inner edge of the base of each section being tapered, a dovetail groove and a dovetail tongue formed at the inner edge of each section, the tongue on one section engaging the groove on the other, a depending part at. the outer end of each section covering the end of the groove in said section, and means for fastening the chair to the tie.

2. Means for fastening a rail to atie of a track comprising a chair formed in sections, each section comprising a base and an overhanging flange, the inner edge of the base of each section being tapered, a dovetail groove and a dovetail tongue formed at the inner edge of each section, the tongue on one section engaging the groove on the other, depending flanges at the outer ends of the sections for engaging the sides of the tie and spikes driven through the holes in the flanges and entering the sides of the tie each of said flanges covering the end of the groove in the section and each section having an overhanging part at one end and a recess at its other end, the recess of one section receiving the overhanging part of the other section.

In testimony whereof I affix my signature.

WILLIAM WILSON BATEMAN.
